$\left\{\begin{array}{ccc}3x-6y=20&|\cdot2\\2x-4y=3&|\cdot3\end{array}\right\\\left\{\begin{array}{ccc}6x-12y=40\\6x-12y=9\\\end{array}\right$

The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.

Answer: B. inconsistent.

How many 6-digit whole numbers have the digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits betw

Yakvenalex [24]

There are 1680 digits 2, 0, 2, and 2 as a 4-digit consecutively ordered block with no other digits between them

<h3>How to determine the selection</h3>

To determine the number of whole numbers, the following must be true

Case 1: If the sequence starts from the first digit

The first digit can be any of the three 2's (i.e. 3 digits)
The second digit can only be 0
The third digit can be any of the remaining 2's (i.e. 2 digits)
The fourth digit can only be the last 2 (i.e. 1 digit)
The fifth digit can be any of 0 - 9 (i.e. 10 digits)
The sixth digit can be any of 0 - 9 (i.e. 10 digits)

So, we have:

$Case\ 1 = 3 * 1 * 2 * 1 * 10 * 10$

$Case\ 1 = 600$

Case 2: If the sequence starts from the second digit

The first digit can be any of 1 - 9 (i.e. 9 digits)
The second digit can be any of the three 2's (i.e. 3 digits)
The third digit can only be 0
The fourth digit can be any of the remaining 2's (i.e. 2 digits)
The fifth digit can only be the last 2 (i.e. 1 digit)
The last digit can be any of 0 - 9 (i.e. 10 digits)

So, we have:

$Case\ 2 = 9 * 3 * 1 * 2 * 1 * 10$

$Case\ 2 = 540$

Case 2: If the sequence starts from the third digit

The first digit can be any of 1 - 9 (i.e. 9 digits)
The second digit can be any of 0 - 9 (i.e. 10 digits)
The third digit can be any of the three 2's (i.e. 3 digits)
The fourth digit can only be 0
The fifth digit can be any of the remaining 2's (i.e. 2 digits)
The last digit can only be the last 2 (i.e. 1 digit)

So, we have:

$Case\ 3 = 9 * 10 * 3 * 1 * 2 * 1$

$Case\ 3 = 540$

The total number of whole numbers is:

$Total = 600 + 540 + 540$

$Total = 1680$

Hence, there are 1680 6-digit whole numbers that the digits
